Musical Fidelity M3I User Manual

Instructions for use
Thank you for purchasing the Musical Fidelity M3i integrated amplifier.
The M3i uses our tried and tested ultra low distortion power amplifier circuitry, which has enough current
reserve to drive even the most demanding speakers with ease. A very low noise and distortion, high-quality
preamplifier completes the integrated amplifier giving a perfect sound from a compact looking full size unit.
The M3i will aesthetically match with present and future M3 series products. Such a combination will yield one
of the best high-fidelity systems available at any price.
Used properly and carefully, it should give many years of outstanding musical reproduction.
Dust regularly with a soft duster or soft brush, but be careful when using cleaning or polishing agents - they
may harm the surface finish.
If there are any questions about the audio system, please consult the dealer who is there to help and advise.
